The situation: Present day. I've got a character who has a medical condition that could cause him to be harmful of others and himself. While he is under medication, certain circumstances will trigger violent outbursts if he isn't careful, and so he has an assistance dog to a) stop him from entering those situations and b) restrain him if he does have an outburst. What I need is info on how a dog is trained to act like in these situations, what kind of commands it might be given, how the dog would detect danger, and so on.
Thanks in advance!
